Summary: The study of hydrogen energy is gaining attention for its effectiveness in achieving net zero and environmental sustainability. Bioethanol is a carbon-neutral fuel for hydrogen production and has potential as a sustainable energy source. This research assesses different routes for ethanol reforming and evaluates the impact of catalyst physicochemistry and experimental parameters on hydrogen production. The findings show that non-noble metals like Co and Ni are more reactive than noble metals in ethanol steam reforming, while the sequence of hydrogen selectivity differs in autothermal reforming of ethanol. The review highlights the importance of sustainable hydrogen production and decarbonization in reaching the net zero target.

Summary: Supercritical water partial oxidation (SCWPO) is a promising technology for converting ethanol into hydrogen and energy efficiently. However, traditional SCWPO reactors have limitations in terms of wall material requirements and system efficiency. This numerical study explores the SCWPO of ethanol with auto-thermal operation, analyzing the effects of different parameters. The results show that increasing ethanol concentration, preheated water temperature, and reactor length can enhance the SCWPO efficiency. This study provides valuable insights for reactor scale-up and system optimization.

Summary: H-2 is a promising renewable energy source, but its production and transportation present difficulties. Distributed H-2 production using liquid H-2 carriers, such as ethanol derived from renewable bio-energy sources, is an ideal way of H-2 utilization. However, the process of steam reforming of ethanol (SRE) for H-2 production is complex, leading to low H-2 yield and catalyst deactivation. This review summarizes recent progress in SRE catalysts and highlights the importance of active metals and supports for achieving high H-2 yield and stability.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
